Hello @Naufal ,
Welcome to the HP Forums!
I understand your notebook display is showing static but has been resolved with a reboot.
There really could be a lot of different reasons this has occured including a driver crash, hardware issues or a mild "hiccup."
If the issue has not returned I would not worry. If this is something that is reoccurring I would suggest updating the drivers for your graphics card. You can download HP drivers from this website: HP - Drivers & Downloads.
It would help to know which notebook you have and the operating system you are using. For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number? To see which version of Windows you are using click here: Which Windows operating system am I running?
If the issue persists let me know which notebook you have and the operating system so I can see what I can do for you.
Please click the "Kudos, Thumbs Up" at the bottom of this post if you want to say "Thanks" for helping!
Please click "Accept as Solution" if you feel my post solved your issue, it will help others find the solution.

    You did not ruin the phone, you will need a sim card to activate the phone and then connect the phone to itunes and do a restore from back up.

  • I want to know what happened to my ipod cause for exemple, when I turn on sometimes all the screen appears with lines and everything look like lines and I have to turn off again..

    I want to know what happened to my ipod, cause after a while that it was off when I want to run in on it gets lines, like if that would be broken and I have to turn off again..

    What generation is your iPod? My sister's 2g/3g(I'm not sure which) was doing something similar, but it would put a different graphic on the screen every time. We took it in to the apple store and they didn't determine what it was. One thing they said to try was to restore it and gradually add content on to see if it's an app or something loaded on it. If that doesn't work then they said it's probably something in the software or firmware. They gave her the option of getting one exactly like the one she had or getting the new one like I have. She ended up getting the new one on sale at target.

  • Mini died, had to reinstall OS X.  Want to know what happened.

    I'm pretty sure that this is a Tiger problem, not a Mini problem. First, I'll give a short version, then a longer version for anybody who's interested.
    SHORT VERSION: I was reading a web page with my Mac Mini, OS 10.4.11, using Firefox. The mouse cursor suddenly vanished, the keyboard wouldn't respond, not even command/opt/esc. After power cycling, I could not even log in. I tried every troubleshooting tip I could find in the Mini manual, and Mac Help on my MacBook. Details below, but nothing worked. I was able to start it in target disk mode. I used my MacBook to transfer essential files from the Mini to an external hard drive. Then I reinstalled OS 10.4.6 using Archive and install, and upgraded it to 10.4.11 again. Most things are working again; occasionally I run into a problem with a specific program and have to reinstall or re-configure. I'm using the Mini to type this.
    I still want to understand what could have happened to cause this sudden crash. Probably "some kind of file corruption", but what could have made that happen, and happen so suddenly?
    LONG VERSION: First, a little history. I've been getting little freezes on this computer for a couple of months now. Up to now, I've been able to unfreeze it by going into sleep mode (holding down power button for only a couple of seconds) and waking it up again. I have run Disk Utility verify and repair about once a month. It usually seems to find some inconsistencies in file names, hazy on details, and "repairs" them. Have not run fsck. I have been using the MacJanitor daily, weekly, and monthly checks; I know these can just be run from the command line too.
    So the computer crashed as described above. The first time I tried to restart it (by power-cycling), it got to a login screen after about ten minutes, then froze for about twenty minutes before I got impatient and power-cycled it again. After that, it never even made it as far as the login screen. Every time, I gave it at least ten minutes to think it over.
    I tried Mac safe mode, and gave that about twenty minutes to do something. It never got beyond the gray screen with the spinning progress disk.
    As mentioned above, I opened it as a target disk, and used my laptop to backup files to a separate hard drive.
    I knew that you could boot up from an install disk, but I missed the Mac help suggestion of running first aid from that disk until after I'd reinstalled the OS. So I missed a bet there, but I don't know if it would have clued me in to what had actually happened.
    As mentioned earlier, I did an archive and install. I'm wondering if there might be some log files somewhere still on my hard drive that would give a clue as to what went wrong. Not really sure where, or for what, to look.
    This whole sudden death thing has been very disturbing. I've had this computer for two years, and I'd like to be able to get at least another two out of it if I choose. I don't expect any OS to be perfect, but this shakes my faith in OS X a bit.
    Rare though Mac viruses are, it occurred to me that I might be one of the rare unlucky ones. Since I didn't do a completely fresh install, if it were that, it could still be there. My Norton subscription expired, and it's been uninstalled. I've been using ClamX on the MacBook, but it won't scan the whole hard drive, you have to know where to look. So if I put ClamX, on the Mini, where would be a likely place to look for a virus?
    I'm assuming that this was an OS rather than a hardware problem just because it was possible to restore, and everything is working again for now. System profiler seems to show all the hardware as it should be. If there are holes in that logic, it would be helpful to know.
    I think that's about it. Thanks in advance to anyone with the patience to read through this mess.

    A lot of things can cause corruption in disk directory data. And it can be a hardware problem with the hard drive, such as bad sectors. It can be caused if the computer ever lost power suddenly, like in a power outage, while it was writing data to the drive.
    I still want to understand what could have happened to cause this sudden crash
    As you said yourself, it was not actually "sudden." You were getting "little freezes" for a few months which progressively worsened.
    Doing an +Archive and Install+ may not fix the problem, if Disk Utility still reports the problem when you do a +Repair Disk+ (while started up from another disk such as your installation disk). If it does not report the problem anymore, the problem was probably fixed.
    A good way to stress test your hard drive and get rid of the problem (if it still exists), is to backup your personal data and erase the drive. But when you use Disk Utility to Erase (reformat) the drive, select the +Security Option+ to +zero out data+. This writes zeros to every sector. Bad sectors (if any) will be mapped out. If the hard drive has too many bad sectors or some other problem, this procedure will fail. Doing the +zero out data+ process takes time.
    If it completes successfully, you should reinstall Mac OS X and your apps, and then restore your personal data.

  • I want to know what happens when the iPad battery gets fully charged and the charger is still connected

    When the battery gets fully charged, and the charger is still connected to the iPad, does the iPad use power from the battery or does it use the charger?

    Install Battery Doctor and see Battery Status or Charging

    System Status will indicate charged when charging circuit is disabled

  • I do not know what happened, all of a sudden Firefox does not want to work anymore. Had been conected to audible. Retried about 4 times.... no luck had to force

    I do not know what happened, all of a sudden Firefox does not want to work anymore. Had been conected to audible. Retried about 4 times.... no luck had to force quit every time. The three Firefox app. into garbage, emptied garbage and redownloaded new version from Firefox. Reinstalled but same thing happened again... no connection.
    What can I do, I like Firefox better than Safari, had it for years on my Mac.
    Please let me know.
    (Note: I have also mentioned this on the automatic response to the malfunctioning).

    Hey.
    I think it might be the problem with one of your plugins.
    Try to uninstall the webbrowser AND remove the storage from Firefox in your user-account (Linux: /home/username/.mozilla). You can check the list of installed Add-Ons in Firefox under "Extras => Add-ons" or by pressing Shift + Strg + A (Linux).

    Assuming you mean that you performed the repair yourself, it would seem that you either obtained a defective screen or you did some sort of damage when you replaced the screen. You can try asking for assistance on ifixit.com, a site dedicate to those attempting their own repairs, or you can take the iPad to a shop and pay them to try to correct the problem for you. Apple will no longer touch your iPad now that you've attempted your own repairs.
    Regards.

    If you have a rescue email address (which is not the same thing as an alternate email address) set up on your account then you can get a clue to what it is, and potentially use it, by going to https://appleid.apple.com/ and clicking 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you should see an option to send security question reset info to your rescue email address.
    If you don't have, or don't want to use, your rescue email address (you won't be able to add/change it until you can answer 2 of your questions) then you will need to contact iTunes Support or Apple to get them reset (which will be by phone as they need to verify your id - we are fellow users here on these forums).
    e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then 'Forgotten Apple ID security questions'
    or try ringing Apple in your country and ask to talk to the Accounts Security Team : http://support.apple.com/kb/HE57
    When they've been reset you can then use the steps half-way down this page to add/change rescue email address for potential future use : http://support.apple.com/kb/HT5312 . Or you could change to 2-step verification : http://support.apple.com/kb/HT5570

    If you experience this issue on a Mac, disconnect third-party devices, hubs, spare cables, displays, reset the SMC, and then try to restore.
    If you are using a Windows computer, remove all USB devices and spare cables other than your keyboard, mouse, and the device, restart the computer, and try to restore. If that does not resolve the issue, try the USB issue-resolution steps and articles listed for Error 1604 above. If the issue persists, it may be related to conflicting security software. If the errors persist on another computer and known-good USB cable, the device may need service.
